Joshua 4:6-7 “that this may be a sign among you. When your children ask in time to come, ‘What do these stones means to you?’ then you you shall tell them that the waters of the Jordan were cut off before the ark of the covenant of the LORD. When it passed over the Jordan, the waters of the Jordan were cut off. So these stones shall be to the people of Israel a memorial forever.”
I notice in this text our Small Catechism question, “What does this mean?”
I do notice that Joshua wrote, “What do these stones mean to you?” – the personal application of meaning are important.
The people are supposed to answer the question with a retelling of the story of how the LORD was at work in the miraculous crossing of the Jordan River. The doctrine of meaning is told through the retelling of the story.
